To all whom "it may concern:

Be it known that I, Fennnvann J. TILLT MAN, a citizen of the UnitedStates of America, and a resident of the city of St. Louis and State ofMissouri, have invented certain new and useful Improvements inCipher-Printing Mechanism, of which the following is a specification.

The primary object of this invention is to provide an improved printingmechanism relative to writing machines, that will rint a series ofciphers with one actuation of an operating key.

Another object is to provide an improved automatic cipher printingmechanism that can readily be attached to the adapted mechanisms of awriting machine.

A further object is to provide an automatic printing rnechani'smthat iscarried by a type carrying bar of a writing machine.

Other and further objects will appear in the specification and bespecifically pointed in the appended claims, reference being had to theaccompanying drawings exemplitying the invention, and in which,

Fi are 1 is "a longitudinal sectional view showing a portion of atypewriting ma chine, and having this improved cipher printing mechanismapplied thereto.

Fig. is a fragmentary horizontal section taken on the line 111-411 ofFig. 1.

Fig. 4 is an enlarged end view of the type carrying bar withthis-improved cipherprinttng mechanism attached.

"Fig. 5 is' a fragmentary plan view of Fig.4.

Fig. h is a fragmentary plan view of a portion of'a platen roller,showing this improved cipher printing mechanism in operetive "relationthereto.

Fig. 7 is a fragmentary view, partly in section, taken on the line VIIVII of fieferring to the dtawings, 1 designates a typewriter theme,- 12-the meveble carriage mounted on said frame, 3 and 4 platen when andtahulating reek, respectively, mounted oat-said carriage.

Swtngingiy mutated in said frame as designated at 5 are the usual keylevers Band arranged above said key levers 6 is a row of tabulating keylevers] which are pivotim-proved cipher printing mechanism in thisinstance 'is operably related to one of the key levers 6, and if it isdesired to mouht this im roved mechanism on an already built ty ewriter,it is thought preferable to eleet one of the ke levers that is e erahl'yrelated to the uppetniost right hand type cair ing bar, said key leverand type carrying ar being generally used for the printing of characterswhich are not veiy mate rial in typewriting, such as the key lever whichis adapted to rint the characters 2 and c, although it is to beunderstood that in new typewriter machines and the like, an extra keycan be added for the manipulation of this improved cipher printingmechanism.

Referring again to the drawings and to Figs. 1, 2 and 3, the key leverdesi nated as A has been elected for the p'urpose of disclosing anoperative construction relative to actuating this improved ci hermechamsm.

Secured to the sill portion 8 of the typewriter frame 1 by a screw 9 isa bracket 10, and pivotallv mounted at 11 to said bracket is a bellcrank lever 12, the upwardly extending portion 13 of said lever having aright angular bent portion 14 formed thereon. which is in the path ofdownward travel of the lever actuating portion 15 of the key lever A.

Pivotally secured to said lever ortion 15 one end of the type her 20,this im roved cipher printing mechanism is mounted in lieu thereof, andcomprises a revolubly mounted roller 23, mounted on an axis 24, saidaxis being secured to one end of the type bar 20, and carried by "saidroller 23 are a pluralit of cipher characters 25..

In rolling contact with the ci her chatesters of said roller 23 is arevolu 1y mounted inking roller 26, mounted on an axis 2?, said axisbeing secured to the type bar to adjacent the roller 28. p

Pivotally secured ates t the depehdin portion 29 of the bell crankleverfia is a re so, the opposite end f said r'od bein secured at 31. toa tabulatihg ke has 32, are

being a plurality of said bars 32, each bar 32 being pivotally securedat one end to its respective tabulating key lever 7 each of said bars 32at their opposite ends bein se cured to a tabulating stop pawl 33, eacof said stop pawls being pivotally mounted as designated at -34, andformed on the upper end of each stop pawl is an engaging portion 35.

Operably related to said stop pawls 33 is a carriage releasing bar 36having a pivotally mounted upwardly extending portion 37 which ispivoted at 37 and is operably re lated to the mechanism, not shown, forallowing the carriage to travel freely to the next tabulating stop inorder.

Referring to the tabulating keys 7 which relate to the mechanismspertaining to the finding of columns relative to entering differentamounts which is a known quantity as regards the listing of items incolumn formation, this improved cipher printing mechanism. is operablyrelated therewith, and for the purpose of more clearly illustrating theoperation of this cipher mechanism, the tabulating key bearing numberone-thousand and designated on the drawing as B, and bar 32 and stoppawl 33 relating thereto being further designated in the drawing as Band B respectively, being elected as coopera'ble with the rod. 30 of thebell crank lever 12.

I In the operation of this improved cipher printing mechanism, assumingit is desired to enter the amount of one-thousand dollars on the sheetwhich is mounted over the platen roller 3 on which the diflerent amountsare tobe entered in a column, the column finder or stop 38 is placed onthe rack bar 4:, and located in order with the decimal tabulating key.

The limiting stop is then. properly located on the rack bar 4 at adistance away from the stop 38 with respect to the number of charactersrelative to writing one-thousand, then the one-thousand tabulating key Bis operated, and bar B connected thereto-is i moved rearwardly, therebycausing the lower end of stop pawl B- to be moved rearwardly, andincidentally swinging the engaging portion 35 of said stop pawl Bforwardly and in the pathof travelof the col umn. finder stop 38.

When the lower end of the stop pawl B was moved rearwardly, thereleasing bar 36 was engaged by said stop pawl and the extending portion37 of said releasing bar was simultaneously disengaged from engagementwith the carriage 2, thereby allowing the carriage to travel in theusual manner until the stop 38 engages the forwardly extending portion35 of said stop pawl B, thereby stopping and holding the carriage 2against further travel, the carriage and sheet mounted thereon thenbeing in a posi tion to receive the entry of one-thousand dollars.

The key lever 6 bearing character 1 is then operated, thereby causingfigure one to be printed on the sheet, then the key designated as A inthe drawings and being operable with the type bar 20 carrying thisimproved oiphering device is operated, the roller 23 thereof bearingagainst the sheet andplaten roller 3, the operator holding said keydesignated as A down, and incidental therewith the bell crank 12 is operated and held down, thereby pushing rod 30 and bar B and moving theengaging portion 35 of the stop pawl B forwardly, and in position toengage the limiting stop 39 on rack bar 4 and next in order.

Incidental with the moving of the lower portion of the stop pawl Brearwardly in the last mentioned operation, the carriage releasingmember 36 was also moved, thereby allowing the carriage to move, andinasmuch as the cipher character roller 23 is engaged against the platenroller 3, said platen roller will cause said cipher carrying roller toturn, thereby printing a series of five ci pher characters after thealready imprinted character one, the limiting stop 39 eventuallyengaging the engaging portion 35 of the pawl 13 and stopping thecarriage from moving immediately after five cipher characters have beenprinted. r

From the aforesaid, it is to be seen after the column position has beenfound, two operations only will be required in order to establish theamount of one thousand as relating to dollars and no cents ($1000.00),the two operations being the manipulation of the key relating to thecharacter one and the manipulation of the key related tothe cipherprinting mechanisms. In order to provide a space or line between thedollars and cents in a column, a spacer member 40 is slidably mountedona guide rod 41, said rod being located behind thefront scale 42, saidfront scale bearing indicating marks corresponding to the indicatingmarks on the top of the rack bar 4. This spacer memher is mounted. inposition or registration with the decimal column, and incidentallycoincidingwith the position of column finder stop 38, the sheet of paperwhen mounted on the platen roller 3 being mounted between said spacermember and said roller. Therefore, assuming that when the ciphercarrying roller 23 has been operated and brought to bear against thesheet mounted on the platen roller 3, said cipher roller will impress orimprint three ciphers before said roller comes in contact with thespacer member 40, said member preventing theroller from printing on thesheet, said roller after riding over said spacer member printing the twociphers denoting no cents.

Assuming it is desired to enter the amount,

, of two hundred twenty dollars and no cents,

- hundreds column is operated, thengthe key lever representing numeraltwo will be operated twice, after which the key A representing theautomatic cipher printer will be stop pawl coiiperable with said key, amovoperated, thereby printing the three ciphers required as denoting twohundred twenty dollars and no cents ($220 00).

For preventing the printing roller 23 from revolving by momentum afterthe same has been operated by the platen roller 3, and for holding saidroller 23 in a set position relative to proper printing of the cipherscarried thereby, a notched wheel 43 ismounted on said roller 23, therebeing a notch relating to each cipher and for engagement with saidnotches is a retarding leaf spring 44, one end of which is secured tothe type bar 20, as clearly shown in Fig. 5.
